FEED-WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent No. 569,362, dated October 13, 1896.

Application filed July 9, 1896. Serial No. 598,516. (No model.)

I?) all whmn it may concern/.-

Be it known that I, JACOB STRUBEN, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a certain new and useful Internal Feedater Heater and Purifier, of which the following is a specification.

My invention relates to improvements in internal feed-water heaters and purifiers for use in steam-boilers.

It has long been known that when wateris first heated in a boiler is the time when the lime and other inerusting material are deposited. It is necessary, however, that the water be thoroughly heated to secure a complete deposit. Numerous devices have been produced for accomplishing this desired result, which have been more or less successful. In all of these after the deposit has been made it has been necessary to clean the parts inside the boiler, and so far as is known to me no means has ever been provided for making that deposit complete before the water comes in contact with the tubes and more or less of the deposit has been distributed over the entire interior of the boiler.

The objects of my invention are therefore, first, to provide an internal feed-water heater and purifier for boilers which can be easily removed from the boiler to be cleaned; sec- 0nd, to provide an internal feed-water heater and purifier in which the water shall be thoroughly heated and all inerusting deposited before it passes to the boiler below, and other objects appearing definitely in the detailed description. I accomplish these objects of my invention by the devices and means described in the following specification and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a horizontal boiler containing one of my improved internal feed-water heaters and purifiers, portions being broken away to show details of construction and the relative position of parts. Fig. 2 is an enlarged detail perspective view of my improved internal feed-water heater and purifier shown resting upon the tubes of the boiler. Fig. 3 is a detail view of a slight modification.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the draw ings, A represents the boiler; A, the boilertubes within A, the manhole. \Vithin the boiler and rest-ing upon the tubes A are two little bases H H, of castiron. On these is supported my improved feed-Water heater and purifier, which is made up of two sections B and B. The section B has a receptacle 0 toward one end. The delivery-pipe B extends down to near the bottom of this receptacle C. An overflow-spout 0 projects out from near the top of the same into the remaining portion of the section, which is formed like a trough,with dividing-partitions extending alternately from opposite sides to form a long continuous passage. A spout F is at the opposite end of the passage leading into the section B, which is of similar construction. Short partitions E E extend between the partitions E, and reach nearly to the top of the water-level between the partitions, and serve to retard the flow of water and secure a precipitation of allinerustingmaterials within it. At intervals the manhole of the boiler is opened and these sections B B are withdrawn from the boiler and the inerusting material removed. All of the coarser material will be found deposited in the receptacle C and the inerusting material will be deposited in the troughs of the sections above described.

The device will work without the partitions E, but will be better with them. It could of course all be made of one section where the boilers are small. lVhere the boilers are very large, it will be necessary to make the same of more than two sections. In that case the receptacle C should be a separate part, as indicated in Fig. SI It should then project down to the boiler-tubes to heat the water as rapidly as possible. The bases H are not an absolute necessity, but serve to hold as purifier-sections above the tubes in the steam. In use it will be found that most of the water will be evaporated from the purifier and heater before it reaches the end of the tortuous passages or troughs and that very little of it will flow out at the depres-v sions F. This secures complete precipitation of the inerusting material. In use it will be found this device practically relieves all back pressure of the pump. 7

The device is also of great advantage when water accidentally becomes low in the boiler, because it will allow it to enter on the purifier and become gradually heated before it strikes the superheated portions of the boiler. This it will be readily understood avoids much of the danger of explosions.

Having thus described my improved feedwater heater and purifier, I desire to state that from my above description it will be noted that it is capable of great variation in its details without departing from myinvention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an internal feed-water heater the combination of the bases H, H, to rest upon the tubes of the boiler; the sections or trays B, B, formed into a long continuous trough by the partitions E, E; subpartitions E, E, extending between the partitions E, to retard the passage of thewater through the troughs; a receptacle 0, to form a connection therewith with a delivery-pipe from toward the top thereof and a supply-pipe D, leading down toward the bottom of the receptacle all coacting substantially as described for the purpose specified.

2. In an internal feed-water heater, the combination of the sections B, B, formed into a long continuous trough by the partitions E,

E subpartitions E, E, extending between the partitions E, to retard the passage of the Water through the troughs; a receptacle 0, to form a connection therewith with a delivery-pipe from toward the top thereof and a supply-pipe D, leading down toward the bottom of the receptacle all coacting substantially as described for the purpose specified.

3. An internal feed-water heater consisting of a box-like casing with alternate partitions extending from opposite sides nearly across the same to form a tortuous trough-like passage,subpartitions between the alternate partitions of lesser height to retard the passage of the water in combination with a supplypipe delivering the feed-water into one end of the same to allow it to pass through the passage to become thoroughly heated as specified.

at. In an internal feed-water heater the combination of a receptacle; a supply-pipe leading toward the bottom of the receptacle; an overflow-passage from the receptacle and a casin g with a tortuous passage into which the receptacle delivers the water coact-ing as specified.

In witness whereof I have hereunto set my hand and sealin the presence of two witnesses.
